Asparagus's growing environment and local conditions

Asparagus Growing Environment and Conditions

The quality of asparagus grown in the north is higher, mainly because there is less water in the dry fields in the north, the growth is slow, and the taste is better. The asparagus grown in the paddy fields in the south absorbs a lot of water, grows fast, but the taste is not as good as that in the north. Chinese asparagus is concentrated in Xuzhou, Jiangsu, Heze, Shandong and other places. In addition, it is also grown on Chongming Island.

Asparagus Growing Conditions

Asparagus is suitable for planting in sandy loam with loose soil, deep soil layer, fertilizer and water retention, good air permeability, fertility, and rich in organic matter. It has a well-developed root system, is relatively drought-resistant, but not tolerant of waterlogging. Pay attention to drainage in the rainy season, and the soil needs to be kept slightly moist during the bamboo shoot harvesting period.

Asparagus growing temperature

Asparagus has strong adaptability to temperature and is cold and heat resistant. The suitable germination temperature is 5 degrees and the suitable growth temperature is 25-30 degrees. If the temperature is higher than 35 degrees, the growth will be inhibited. In high-altitude cold areas, when the temperature is below minus 33 degrees and the thickness of the permafrost layer reaches 1 meter, it can still safely overwinter. Although the yield is low, the quality is better.

Asparagus growth process

1. Seedling stage: After asparagus is sown, it will germinate soon. When it grows to a certain stage, it needs to be transplanted. This stage is called the seedling stage, which lasts about 2 to 3 months.

2. Juvenile stage: After asparagus is planted, it is in the juvenile stage until the early stage of harvest, which lasts about 1-3 years. In the south where the conditions of fertilizer and water are good, the time will be slightly shorter. This stage is a rapid growth period, the aboveground stems continue to increase and grow thicker.

3. Adult stage: The period from the second year after asparagus goes into production to the aging stage is very long, usually 6-10 years, or even 15-20 years. This is the most vigorous growth period in the life cycle, with many tender stems of uniform thickness produced, making it the peak production period for asparagus.

4. Senescence period: After vigorous growth and harvest, asparagus will enter the senescence period. The growth rate will slow down, the speed of spreading to the surrounding areas will slow down, the stems and leaves will find it difficult to grow, the yield will decrease, the storage roots that have grown previously will slowly wither, and the bulbils will shrink or even die.
